Software Development. I won't do fixed price contracts unless it's really simple. Always time & materials.

Home renovation. You'll get a quote, but the final price can be way higher. Any service when you are dealing with unknowns, the price is going to have to be flexible.

You'll at least quote an hourly rate, a doctor won't do that.

For super obvious reasons. A developers cost is almost entirely their time. That is the "unknown" for a developer.

For a doctor, the unknown includes many possible things like drugs administered, blood administered, emergency care, hospital costs, etc. It's not as simple as an hourly rate estimate, unfortunately.

I mean, every time I've dealt with a contractor it's time and materials. And the markups that hospitals charge on materials would be considered fraudulent by a court if someone tried to pull that as a freelancer.
